FIG. 2 is a greatly enlarged rear elevational view thereof broken away in the middle for convenience of illustration; and,

FIG. 3 is a perspective view thereof on a greatly reduced scale in position of use on a vehicle which is shown in broken lines for illustrative purposes only and forms no part of the claimed design.
